It is well known that when writing checks, bank drafts and the like by hand there is no suficient security against forgery or altera tions, as any kind of ink can be blotted out 8 by a suitable chemical reagent For this reason the method of typewritm the figures and letters with fatty mks has n resorted to and the characters im ressed by the type-v writer are generally ma e to cut or perforate 10 the check or draft and these cuts or perforations are entered by the ink. Howevernot even this way assures an absolute security against forgery, because forgers have found it possible to alter the amounts by adding words or figures or by replacing words or fi ures with words or figures cut out from ot er checks or drafts.

The ap aratus' according to the-invention has the o ject to eliminate the possibili of forgery on'checks, bank drafts and the ike.

It provides essentially for the amount being printed with figures differing from see other in shape and size according to the scale showing the value of the draft, for example so that the height of the res decreases gradually from the hun .of thousands to the single units and that all intermediate spaces are occupied by figures or si sugh an arrangement it is not pose: Is to add ot er is occu led, nor is it ssible to put into the place 0 a figure of a igher order a figure of lower order out out from another draft, because such figure has a different shape and size.

Where the draft has not suflicient fi res to fill in the entire space provided for t e sum, the em ty space may be occupied by nou hts, asteris or signs. It is also advisab e to provide for the writingwhich indicates the value of the draft being immediately pre ceded'and followed by special signs; the, sign in front of the sum may indicate the currency, and every sin le figure may be plawd between small lines a V0 and/or below it.

A further security against forgery is obtained in case the space provided for dividin the units from the fraction is made cit er narrower or wider than the spaces prothe procedure above described is to arrange of units they represent in the final figure With use as the whole available space vided for the figures, seas to render it impossible to insert in such space a figure which might alter the amount written on the draft. he most convenient method of realising the t pes for (printing the figures or numbers on t e outsi e surface of narrow circular drums which are only slightly wider than the t and whichare arranged one beside the ot er and may rotateon the same horizontal Q shaft,- so that these drums can be brought into, and secured in any desired position, the

t being laced in a line'on the lower sl d of the ums when the printing is to be done. One of these drums may be fitted e5 with the types for the signs indicating vanous kinds of currency, so that the same apparatus can be used or writing various currencies. An intermediate drum, which may be made narrower or wider than the other drums carries-the abridged signs indicating the fractions of the unitary value, or its place may be occupied by one single sign or mark if the apparatus is used for printm one kind of currency only. The signs f0 owing the finalfi re may also be of one sin le type. a The rums may easily be rotate by means of levers which pass to the outside through the casing or cover of the apparatus, and these levers have marked on them the figures and signs carried by the respective rum.

After the various figures and signs have i been brought into line so as to reproduce the amount to be printed, the shaft carrying the drums isv pushed by suitable. mechanism a ainst the draft or the like to be printed, w ich may be placed one fiat surface, a roller, or the like support, or thedraft to be printed may be pushed by the said mechanism against the drums, the mechanism being controlledvby means of a lever, a crank, a pedal, or in any other way, or it may be driven by a motor. The printing pressure should be regulated by a suitable spring instead ofby hand pressure. The above described arran ment allows the figure representing the va us of the draft and the like being rapidly formed and being rinted any number of times with-- out any a ditional operations. It has thus on'the counterfoil without any danger of incurring into errors and that many drafts having the same va ue may be printed in a rapid succession.

For this purpose it is advisable to provide the a status with an inkin pad by means of w 1011 the types are inked each time the drums are moved for a printing operation. In the accompanyin drawings, Figs. 1 and 2 are respectively a si e and a front view of one form of apparatus for carrying this invention into practise.

Fig. 3 is a view of an amount as printed by the apparatus.

a and b are two shafts. The shaft b carries the drums a which are fitted along their periphery with the types of the figures and si s. The drums ma be,rotated by means 0 levers t and are hel in place by sprin u arranged in suitable seats. The shaft is en rted by two bearings e e which may be sh1 ted in a vertical direction. The shaft 0 may be rotated by a crank handle (I and carries the cams 0-0 which serve to push the spindle b with the drum downwards for the printing operation.

Springs 9 g serve to carry the shaft 6 and Q the drums upward. f is a stationary organ the ty carrying the type for indicating the fractlon of the currency, h and i are gear wheels which transmit the movement of the-crank d to the on small springs or other elastic means, not shown in the drawings, so that it can sli htly shifted downwards.

e printing surfaces of the t s on the drums and of the small block ma smooth or have lines or recesses so as to o tain on thepaper either an ordinary print or perforations or cuts intowhicht e ink penetrates more easily. Y

What I claim is:

1. A machine for printing the amount on checks and the like comprising a series of type-carriers, each diflerent from the other, and destined to print the cipher of a determined order in the number indicating the amount in whlig the check is drazvn, each type-carrier 0. ca types 0 ten ciphers, these types each being of graduated sizeand diflerent in size with respect to adiacent types, and being of the same size on the same type-carrier, the size of the type indieating the order of the cipher which the particular type-carrier is destined print in the number. a

2. A machine for prmting the amount on 1,ess,ae1

checks and the like according to claim 1 in which the type-carriers comprise wheels rotating aroun the same axis and independent ofeach other, the types being disposed on GHINO nfi GIORGIO.
